CALENDERINGHWACHINE.

SPECIFICATION forming part of Letters Patent No. 695,107, dated March11, 1902.

Application filed October 8, 1901. Serial No. 77,998. (No model.)

To all whom, it may concern.-

Be it known that I, PATRICK MILLAR MAT- THEW, a citizen of the UnitedKingdomv of Great Britain and Ireland, residing at Victoria India RubberMills, Edinburgh, county of Mid-Lothian, Scotland, have inventedImprovements in Calendering-Machines, (for which application for patenthas been made in Great Britain, No. 4,360, dated March 1, 1901, and inGermany, dated June 20, 1901,) of which the following is aspecification.

This invention relates to calendering-machines of the kind employed forcoating fabrics with rubber and in which the rolls are arranged torotate all at the same speed for applying what is known as a calenderedcoating or at different speeds in order to apply a friction coating ofrubber, which is driven into and through the fabric.

The ordinary rolls employed for calendering and friction coating fabricswithrubber are adapted only for applying a coating of rubber to theentire surface of the fabrics passed through them. The rolls beinghoused in side frames are driven by gearing outside these frames and areunsuitable for friction coating or calendering only a marginal stripalong the edge of the fabric to present afresh and strongly-adhesivesurface which may be advantageously used in uniting together fabricsforming parts of garments and in the manufacture of boots and shoes tofacilitate the attachment of rubber soles and of goloshing-strips tocanvas uppers so coated.

According to my invention a calenderingmachine for coating a marginalstrip of a fabric with rubber is so constructed that the rolls overhangor extend outside one of the side frames, while the driving-gear isplaced on shafts extending between the side frames, and a tableprovidedwith a guide is placed alongside the overhanging rolls to facilitate theleading in of the edge of the fabric, the guide being preferablyadjustable, so that any desired marginal width of rubber coating may beapplied.

The invention is illustrated by the accompanying drawing, whichrepresents the improved calendering-machine in elevation.

As shown by the drawing, the improved calendering apparatus comprisesthe usual side frames F for carryingthe rolls,which are, as usual, threein number and hollow; but in lieu of extending between the side framesthese rolls H H H are so constructed that they overhang or extendoutside one of the side frames F. The steam and water pipes I forheating and cooling the hollow rolls are connected at the opposite endsin the usual way. The driving gear composed of the usual spur-wheelsinstead of being outside the side frames F is placed on shafts extendingbetween these frames. The central roll H is arranged to be driven at auniform speed with the other rolls H H for calenderingv or at higherspeed for friction-coating fabrics by providingtwo driving-pinions G Gon the shaft J of the roll H and arranging them to slide on afeather-key on the shaft to bring into gear either of two sets K L or KL of driving-wheels on the shafts of the rolls H H Alongside theoverhanging rolls H H H is placed a table M, upon which the fabric to becoated is laid, and a suitable guide, such as N, preferably adjustable,may be provided to facilitate the leading in of the edge of the fabricbetween the rolls H" H so that the desired marginal width of rubbercoating may be applied.

The calenderin -machine is operated. in the ordinary way, the rubber toserve as the coating along the edge of the fabric being fed in by handbetween the upper rolls H and H and carried around in the form of a thinlayer on the central roll H, by which it is transferred to and pressedinto the margin of the fabric passing through between the rolls H and HHaving now described the invention, what I claim, and desire to secureby Letters Patent, is

1. A calendering-machine constructed with the rolls overhanging one ofthe side frames and their driving-gear between said frames, said machinebeing adapted for applying a friction or calendered coating of rubber tothe marginal edge of a fabric as set forth.

2. In a calendering-machine the combination with the side frames ofdifierential-speed rolls overhanging one of said frames,drivinggearbetween said frames and a table placed alongside said rolls tofacilitate leading in the marginal edge of a fabric between the rolls.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

PATRICK MILLAR MATTHEW.
